I have MyCommand and Multiverse. Now I would now set the command /mycmd-blockset add /mv tp arena to a button. But if the user press always comes: you can't do that. Insufficent permission. I have already set the right hand at Player2 in PermissionEX: - multiverse.portal.access. * - multiverse.core.spawn.self - multiverse.teleport.self.Arena - multiverse.teleport.other.Arena Nevertheless, the button does not activate ... has one a suggestion?
